To all whom it may concern:

Be it known that I, MATYAS SCIHEBEND- REIN, a subject of the Emperor of Austria- Hungary, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Wheat-scouring Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part My invention has relation to improvements in wheat scouring machines; andit consists in the novel construction and an rangeinent of parts more fully set forth in the specification and claims.

In the drawings, Figure l is a vertical transverse section on the broken line 1 1 of Fig. 3; Fig. "2 is a perspective detail of one of the series of deflecting ribs and the con trolling bar attached thereto; Fig. 3 is a vertical longitudinal section on line 3-3 of Fig. 1; andl igl e is a sectional detail on line H of Fig. 1 showing the conveyer for removing the heavy. particles of the impurities.

The object of my invention is to construct a machine which will effectively scour wheat as it leaves the separator and prior to its driven by a beli-pulley B, the shaft hav ing secured thereto, at opposite ends within the casing, the heads or disks 2, 2, which are provided with tangentially disposed brackets or arms 3, 3, arranged opposite onemnother, each pair of brackets having secured v thereto the longitudinally disposed plates or heaters l. The casing is provided at one end above the shaft 8 with an inlet chute l, and at the opposite end below the shaft with an outletchute O. The casing C and its lining l have a section thereot' removed, the

pointed out in the opening thus left being covered by a perforated plate or sieve a convexedontw'ardly \(Fig. 1), there being secured above the sieve a longitudinally disposedbar .5, whose opposite ends are fastened in any -mechanical-; manner to the heads of the casing or cylinder C. Through the supporting bar 5 are passed the cylindrical rock-stems 6, of assries of crescent shaped deflectors 7, lying close against the inner surface of the sieve a cs each stem 6 being provided with a collar 6 to insure support therefor on the barb. (To the outer reduced end of each rock-stemti is secured an arm 8, theseveral arms-being connected toa common controlling link or 9 rod 9, one end of which passes freely through the head or end of the casing G and terminates in a loop or handle 10, as shown.

Mounted above the casing C-is an extension 11 with which is formed the central '1 enlarged fan casing 11 for the blades fan F, the shaft 12 i of the latter, being mounted in braclrets 13, .13, bolted to:l:he sides of the extension 11. The fan-shaft 12 is provided at one end with .apulley 1%, B from which runs a belt 15, the latter assin over a pulley 16, on the main drive-s aft. Leading from the fan casing is an exit flue 17. The walls of the extension 11 incline-to meet the walls of the dust compartment 18, the lower end of which tapersint'o-the form of a hopper (Fig. 1) to catchthe heavy particles of the impurities. the base of said hopper being provided witha spiral'conveyer 19, the shaft 20 of which is driven by a. belt 21 passing over the'pulleys 22 and 23, carried by the shafts S and 20 respectively. The spiral conveyer discharges its material through the chute 0., The scoured Wheat in approaching the outlet 0, passes over a ledge 24, below the baffle plate or Wall 25: the wheat passing onto the ledge through the opening 0 formed in the rear wall of the outlet line Owhich latter constitutes the lower terminal'of the inclined fine 26 The upper terminalof the flue 26 takes the form' of a longitudinally disposed flue or extension 26, which discharges into the chamber 18 at-the base of the casing l1, approximately -below the fan F. (F g. 3.) The operation of the machine may be described as follows:--- Rotation. being imparted to the drive-shaft S, the fan F and the conveyer 19 will be driven throughthe belt connections described. The wheat is dumped or fed in attli inlet end Lwhereupon elliciently against thelining 1,

the rotating heaters or blades/l will.rub thesame against the surface 0f -the carborundam lining l, the length of time the grain remains in the cylinder C depending on the angular disposition of the deflectors or ribs 7, relative to the axis of the cylinder. The operator, by seizing the handle of the rod 9, can rock the several stems 6 about their axes so as to set the deflectors 7 to any angle: and that angle determines the rate at which the grain is advanced from the feed to the discharge end of the cylinder. By increasing or decreasing said angle the rate of discharge will be accordingly more 'or less rapid. As the grain is thus carried around between the heaters or blades 4 and the lining 1, the chaff, straw, beards, "and other impurities become separated from the grain, and broken up sufficiently to pass through the reticulated or perforated plate or sieve a, (which by the way may be made of Woven wire) and is drawn up by the suction of the fan through the compartment 11, and through the fan casing, and out through the exit fine 17, the cleansed and scoured wheat. dropping through the opening 0 onto the ledge 24, thence through the discharge mouth or outlet 0, where it is caught in any suitable receptacle (not shown). As the secured wheat thus travels along the ledge 2%, any light particles accompanying the same will be drawn up through the line 26, 26 into the fan casing and out; and finally such particles as escape the rising air eurrei'its by reason of increa ed weight of the particles will drop down to the bottom oi the compartment 18 whence they are discharged by the spiral conveycrlt) toward and into the chute O and disposed of in any suitable manner.

By disposing the blades or heaters l tangentially as shown, the'grain projected more and thus un dergoes an attrition or rubbing which it would receive less effectively were the blades disposed radially. Besides, in a tangential disposition, each blade serves to support the grain through a greater angle of rotation before dropping it than would be the case were the blades set radially. The machine, while primarily designed to scour wheat, ma of course be used for cleaning claim is 1. In a grain scouring machine, a suitable cylindrical casing having an inlet and an outlet, and having a portion of its peripheral wall removed, a reticulated plate or sieve mounted in the opening left by said removed portion and curved in the arc of the cross-section of the inner surface of the casing, a rotating member confined within the casing, a series of tangentially disposed boaters on said member for scouring the grain, a series of adgustable ribs distributed along the inner surface of the sieve and curved to conform with the cylinder walls, and means for adjusting the angular disposition of the ribs relatively to the axis of the casing, whereby the gain is advanced at any predetermined rate of speed toward the outlet.

2. In a grain scouring machine, a suitable cylindrical casing having an inlet and an outlet, and having a portion of its peripheral wall removed, a reticulated plate or sieve mounted in the opening left by said removed portion and curved in the arc of the cross-section of the inner surface of the casing, a series of rotating tangentially disposed blades operating in proxnnity to the inner surface olt'the casing, a series of ad justable ribs distributed along the inner surface-ot the sieve and curved to conform with the cylinder walls, rock-stems connected to the centers of the ribs, a longitudinally disposed bar forisupporting the stems, arms on the stems, alinh or rod pivotally connected to the several arms, a suction tan or exhaust for removing the light. impurities separated from the grain through the sieve and from the point of the charge from. the casing, and an intermediate compartment between-the exhaust and the point of discharge through which the impurities pass on their way to the exhaust.
